A double-scrim belting (10) is described having a first woven scrim (12) and a spaced apart and substantially parallel second woven scrim (14) connected by staple fibers (16) consolidated together through entanglement and integrated with the scrims through entanglement, both entanglements being of the kind typically produced by needling. If desired, a non-woven web of staple fibers is needled to the outer surfaces of the scrims and the thusly formed belting is completely encapsulated in a matrix of elastomeric material (36). To further strengthen the connection between the scrims (12, 14), the scrims are additionally joined together by binder members (42) which extend in a direction of the thickness of the belting. If the belting is intended to be used to convey food grade products, preferably an antibacterial agent is incorporated into the elastomeric material to inhibit bacterial growth.

[ What is claimed is:] [1.] A conveyor belting, which comprises:(a) at least two generally planar and parallel scrim means, each comprising a plurality of substantially parallel textile yarns;(b) fibrous material provided intermediate the at least two scrim means, the fibrous material being in the form of discrete staple fibers consolidated together through entanglement of the individual fibers and the discrete staple fibers being integrated with the yarns comprising the scrim means by entanglement of the fibrous material therewith to connect between and thereby join the at least two scrim means, both entanglements being of the character produced by a needling operation;(c) a multiplicity of binding means extending substantially in a direction of a thickness of the at least two scrim means joined together by the entangled staple fibers to reinforce the connection between the scrim means; and(d) a polymeric material encapsulating the adjacent scrim means, the connecting fibrous material and the binding means.
